I never liked the sub much.
I liked the look of the "ball speakers" buyt they don't sit on the shelf all that well. There is an "o-ring" low tech solution that is supposed to keep them in place but it never really worked that well.
I had to make custom mounts for the rear speakers so I could be cool like Ken and have 5.1 in my bedroom. That ended up being expensive.
They sound pretty good but the sub was hard to match with the speakers for me.
